 It's been a years-long ride for Cedar Fair and Six Flags executives to finalize a merger. They announced Wednesday they expect to seal the deal July 1st. They will operate under the Six Flags name. Cedar Fair executives say they plan to make upgrades, add new rides, and improve food and beverage options at parks. The company will own 27 amusement parks, 15 water parks, and nine resorts across the U.S., Canada, and Mexico.
